Found a small bug--maybe someone saw it before. If you start a new game and try to move a pawn from a2 to a8, the promotion dialogue pops up before you are informed it is an illegal move. In any case, it's an excuse to write to say thanks for something that can let me look at a game quickly when I need a short work break.
Also, thanks for the Vista fix. I have had/still have problems with Vista with other software/websites(I am very close to re-installing XP on my home machine) but am glad you made one less nuisance to deal with.
